6/21/26: As most of you know, I previously installed power disc brakes, a PCV system and also have the original vacuum wipers. Ever since I installed the power disc brakes, I’ve been trying to figure out the best way to handle the original vacuum wipers.
My initial plan was to install an electric vacuum pump to keep them running independently. I ended up picking one up off Amazon for about fifty bucks, but once I hooked it up to test the noise level, I was really disappointed—it was incredibly loud. It definitely took the wind out of my sails regarding that particular plan.
I was talking to a good friend of mine about it, and he was adamant that the engine should have more than enough vacuum to handle the power brakes, the PCV system, and the wipers all at once. I decided his suggestion was at least worth a shot, since I had all the fitting needed to tee it in.
It seems like a solid solution on paper, but only time will tell if its tolerable under load. I’m still a long way from a road test, so I’ll have to wait and see how they perform once I’m actually out on the street.
I’ll be sure to let you know how it turns out once I finally get it out of the garage.
